Summary:
Lichens are the dominant form of vegetation on eight per cent of the
earth's land surface, and a major contributor of nutrients to barren
environments such as desert and tundra. They are a key indicator of
ecological change and a warning signal of decline. Use the internet to
learn about them and use them to monitor environmental health where you
live.

"No work of fiction that turns its back on life or that is
incapable of illuminating life has ever attained
durability."
